Information on calibration gases
●
Factory calibration: Mixtures of dry N
2
and O
2
.
●
Humidity / CO
2
concentrations: 0%.
●
Gases recommend for adjustment: Nitrogen gas mixtures.
●
When using the sample gas cell: Volume flow for calibration and adjustment about
0.5 l/min higher volume flow for shorter response times. The higher the gas volume, the
higher the gas pressure.
Select an adequate tubing size for the escaping gas.
6.4.3
Adjustment
SICK recommends a one-point adjustment with a dry O
2
/N
2
gas mixture with an O
2
concentration of about 21% O
2
for this TRANSIC151LP variant.
The adjustment gas concentration must be in both the probe and the enclosure of the
TRANSIC151LP. Further information,

6.4.4
Adjustment options
– One-point adjustment (O
2
concentration at 21.0%) via the keypad.
– Restoring factory calibration.
NOTE:
Allow enough time for the gas concentration to stabilize when doing calibrations/
adjustments.
